Abstract: PURPOSE:To obtain a dry etching apparatus by means of which the uniformity inside a face can be set to a good condition by a method wherein solenoid valves which open and shut a plurality of etching-gas blowoff holes are installed respectively at the blowoff holes which have been made in an upper-part electrode. CONSTITUTION:Gas blowoff holes are arranged on a wafer corresponding to a position <a> in the figure. When a polysilicon film is first etched at a pressure of near 12Pa, an etching rate in the central part of the wafer 7 is slow at the pressure of near 12Pa. As a result, only a solenoid valve 5 in a position (b) is opened and the film is etched. A pressure of near 16Pa is a region whose uniformity of the etching rate is good. As a result, solenoid valves 5 in individual positions (a), (b), (c), (d), (e) are opened and the film is etched. In a pressure region of 20Pa or higher, the etching rate at the outer circumferential part (position (e)) of the wafer 7 is slow. As a result, only the solenoid valve in the position (e) is opened and the film is etched. Thereby, when positions of the gas blowoff holes are changed at the individual pressure regions, an etching operation whose uniformity is good can be executed at respective pressure positions.
